Application led November 25, 1907. 'SerialiNm 403,729.-

Be 'it known that I, ARTHUR CLARIDGE, acitizen of the United States of America, re-

at lthe city. of Baltimore, State of invention to be hereinafter described an claimed, provides means 'whereby enam- :securedto a support and the' enamel tected from stress due to fastening.

' l :e ii-"plates used as signs, labels, &c. may be PTO- The nature of my device is such that the enamel is not yonly' protected from stress transmitted by the fastening means, but that discoloration of the enamel the fasteners is prevented.

. The-invention also operates to prevent discoloration by ,making it feasible to cover the entire surface of the metal plate with enamel and by-protecting the latter from ury.

Various deviceshaving this end in view areiu'iise. I In one of these the metal Iplate is. provided with bosses extending through eledsign,

the enamel,l and apertured to receive fastening screws. l In order to prevent fracture of the enamel by the pressure of the screws, the ends of the bosses are left bare. As the plate is generally 0f iron, or some easily corroded metal, the enamel surrounding the boss bey comes discolored. Further, the body ofthe screws comes into intimate contact with the enamel, and if madey of corrosive material furnishes another source ofldiscoloration.

g-Referring to .the accompanying drawings, Figure `l is a supp ed with the protecting means I. which constitutes the subject matter'of my invention. Fig. 2 is a cross section taken through the fastening means. Fig. 3 is an `enlarged. axial cross section of one of the protectinv sleeves.

A' rlate (l) of iron or other suitable materialp erforated at convenient points, indi- 'cated liy reference characters 2 is com letely coated with enamel, 'the inner-su ace of the a ertures, as well as the rest of the plate eing completely covered. Cylindrical sleeves (3) of external diameter less than the internal diameter of the openings in the enameled plate and composed of non-corrosive material, are inserted in the openings. The ends of these sleeves are turned over sub. stantially at right an les to the Acylindrical body and arallel to t e surface of the plate forming anges (4) separated by a space'l vby contact with prspective view of the enam.

- extending' throng greater than the entire thickness of the plate, including the metallic portion and othcoatings of enamel. The sleeve is so constructed as to offer sufficient resistance to the insertion of a screw or nail to space the head 'of such fastening means a distance thickness of t e sign and the lianges.

When it is desired tofasten the sign to a support, screws (5) of a suitable-size are 'in.

serted in the sleeves and turned tilltheir heads engage 'the flanges, and attach `the sleeves rigidly to the support (6).l 'By this means the sign is held in position as securely as may -be desired, and the enameled-surfaces "are protected from the stress exerted by the screw by the resistance which the sleeves interpose between the screw head and the support. The sleeves also furnish a non-corrosive covering for the screw,so that any prod uctsv which may result lfrom its decomp'osition do not come in contact with theenam eled surface to discolor it. By using this type of protector sleeve itis made feasible to -from'the su po'rt greater than the entire cover the entire surface of the metal plate with the enamel and leave'no exposed surface to corrode and discolor the sign, atthe same time no danger of injuring the enamel is incurred. f

Having thus described my invention, what I claim and desire to secure by Letter'sPatent is: V

l. The combination of a support', a metal plate coatedwith enamel and having a suit` 'able opening, a `sleeve of length greater .than the combined thickness of the plate and enamel, in the'opening and fastening'meansl extending through thel sleeve and engaging the su port. 2. he combination of a support, a metal plate coated with enamel, and having suitableopenings, a sleeve oflength greater than the combined thickness of the plate and enamel, in'each o ening and fastening means extending throug the sleeve andengaging the support, a head .on the fasteningmeans engaging one end of the sleeve andi pressing the other end f the 4sleeve against the' suport. y p 3.' The combination of asupport, la plate coated with 'enamel and having' suitable o enings, a flanged sleeve of length greater tllfan the combined thickness of the plate and "enamel, in each o ning and fastening means Ill the sleeve and engaging the support.
